New electromagnetic flowmeter suited to all water and wastewater applications

Endress+Hauser recently launched its Proline Promag W 300/500. Promag W 300 is the new compact version with multiple I/Os, while the existing remote version, Promag W 500, is now available as a digital remote transmitter. The digital remote transmitter allows a maximum connecting cable length of up to 300 m (1,000 ft).

The Promag W flowmeters feature all options to fulfill the requirements of the water and wastewater industry. They possess the necessary custody transfer approvals, Ex approvals as well as IP68 for underwater and buried installations. The devices are available with welded flanges as well as with lap-joint flanges. The 0 DN inlet option allows for guaranteed measurement performance of ±0.5% or better even when the meter is installed immediately after any obstruction. The three liner options, hard rubber, polyurethane and PTFE, have all necessary international drinking water approvals such as KTW/W270, WRAS, NSF 61 und ACS. The Promag W sensor is available in line sizes starting at 1” up to 90”. The device is calibrated according to ISO/IEC 17025.

Proline 300/500 transmitters include a web server as a standard. Using a standard Ethernet cable and a laptop – or wireless over WLAN, users have direct access to all diagnostic, configuration and device data without additional software or hardware. This enables targeted and time-saving maintenance and service.

Heartbeat Technology testing function is integrated into all Proline measuring devices and enables permanent self-diagnostics with the highest diagnostic coverage (>95%) as well as a TÜV-tested, metrologically traceable device verification without process interruption. All of this reduces complexity and hazards in a plant and increases its reliability and availability.

The one-of-a-kind data storage concept (HistoROM) ensures maximum data security – before, during and after service. All calibration data and device parameters are stored securely on the HistoROM data storage module and are automatically reloaded after maintenance work. The HistoROM data storage module stores up to 20 timestamped event messages such as diagnostics and configuration changes. If the optional Extended HistoROM application package is selected, up to 100 of these events will be stored, along with the option to record up to 1,000 measured values via 1 to 4 channels. Installing spare parts is easy, saves time and thus reduces unnecessary downtimes.
